This was the third major inquiry announced in the last week, with Secretary of State Michael Gove’s appointment of counter-terrorism expert Peter Clarke to head the Department for Education investigation and a City Council probe led by former teacher Ian Kershaw.

Mr Mahmood said: “We have three different people leading three different inspections. There are also police investigations.

“There is a risk of over kill. This just creates confusion, leads to duplication and causes delay.

“What happens if they come up with different recommendations? Whose do they implement first? It would be better if there was a single inquiry which was transparent, effective and finished quickly.”

He said that they need to ensure that the issue is dealt with by the time the new intake of pupils start school in September.

The MP remains convinced that there is a concerted plot to infiltrate secular schools in majority Muslim areas and impose hard-line Islamic teaching ‘by stealth’.

The alleged Trojan Horse plot was outlined in an anonymous letter sent to the authorities which claimed that hard-line Muslims were putting themselves into positions of power in schools in Birmingham, such as on governing boards, and appointing like-minded individuals to teaching positions while undermining those who do not share their view.

The city council has been indundated with more than 200 claims and allegations and a total of 25 Birmingham schools are now under varying degrees of investigation.

The Muslim Council of Britain has been particularly critical of the appointment of a counter-terrorism expert to head the Government inquiry - saying there is a risk of a ‘witch hunt’. A spokesman said: “It is therefore critical that any investigations are seen to be impartial and not victimising a community.

“Such an appointment only re-enforces such notions, and once again, our community is seen through the narrow prism of security and counter-terrorism."
